-The wood wool panel (or any other type of panel) can be applied under the ceiling at some distance <sup>[[1)|]]</sup>  and the resulting hollow space can then be injected with blown-in insulation, in which case any pipe attachments, cable ducts etc. will be less of a problem. This method is particularly suitable for ceilings that are less even (e.g. old vaulted ceilings).

 [{{ :picopen:insulating_the_basement_ceiling_02.png |Fig. 2: The solution recommended by the association for blown-in insulation for a vaulted ceiling: lagging/formwork is screwed on to lathing/battens affixed at right-angles to the steel joists. If there is less space available, this can also be a phenolic foam board, which already has a basic insulating effect. The resulting hollow spaces are filled with blown-in insulation material. Mineral wool and cellulose are suitable as blown-in insulation materials. }}]
